I finally acquired a copy of all my
Usenet posts for all time; such fun finding my
first post!
But the graph of my posting activity is sad:

Most posts are before summer 1994, when I graduated from college. Usenet was a hugely important
thing for me, both a technical touchpoint as I was learning Unix and
the Internet and a social touchpoint as I was coming out.
Now mailing lists, the Web, and blogs have replaced Usenet as the
primary online social medium. I miss the exclusive club we used to
have.
